Thanks Alec, I think this describes my issue too. I've been running
backports kernels for sometime, I still have 3.16 installed but
haven't tested LIRC under it (there's been a lot of other package
updates and I wonder if it will even boot anymore). Booting into the
4.4 backports kernel fixes my problem.

I managed to get some output (eventually) on ir-keytable, which at
first with 'ir-keytable -v' returned nothing on key presses.
Eventually I managed to get values returned. It was either due to
writing [ir-keytable -w] the table from /etc/rc_keymaps/mce-usb [or
something along those lines] or from running ir-keytable with the
input device specified (when run in the past I thought it detected
automatically?). At that point the directional key functionality
returned  I didn't check them all but the ones I spot checked appeared
to be the same. If I get some time this weekend I'll try your 0.9.4a
package.

Appreciate it.

Family is away so I resolved this in the riskiest manner possible:
upgrading from jessie to stretch (actually I was fairly sensible and
did it on a rarely used desktop system before doing my main system). I
can confirm that LIRC is working under the 4.6 kernel under stretch.
Obviously Some other things broke in the process (KDE related), but so
far MythTV appears to have survived and works. I'm going to call it a
win because it resolved one other nagging (not MythTV related) problem
too ;)
